Macroeconomics
The branch of economics that studies economic issues and problems at the level of the economy as a whole, such as total employment, aggregate demand, and general price level.
Final Goods vs Intermediate Goods
Final goods are meant for final consumption or investment and have crossed the production boundary. Intermediate goods are used as raw materials or for resale within the same year and remain within the production boundary.
Consumption Goods vs Capital Goods
Consumption goods satisfy human wants directly (e.g., food, clothing), while capital goods are durable goods used in the production of other goods and services (e.g., machinery, plant).
Stock and Flow Variables
A stock variable is measured at a particular point in time (e.g., wealth, capital), whereas a flow variable is measured over a period of time (e.g., income, investment).
Depreciation
The expected or unexpected loss in the value of fixed assets due to normal wear and tear, passage of time, and expected obsolescence.

Frequently Asked Questions
What is the difference between microeconomics and macroeconomics?
Microeconomics studies individual economic units like a single consumer or firm, while macroeconomics studies the economy as a whole, focusing on aggregates like national income and total employment.
Why is the same good sometimes classified as intermediate and sometimes as final?
Classification depends on the ultimate use of the good. If sugar is bought by a household for tea, it is a final good. If sugar is bought by a bakery to make biscuits, it is an intermediate good.
What is the difference between stock and flow variables?
Stock variables have no time dimension and are measured at a specific point in time (e.g., bank balance on March 31). Flow variables have a time dimension and are measured over a period (e.g., monthly salary).
